The aim was to study the main qualitative and quantitative characteristics of phytoplankton in the studied areas of surface water bodies of the Bukhara region. It was found that in the studied water bodies (Tudakul lakes and Kuyumazar reservoir), Bacillariophyta (34 species), Chlorophyta (20 species), Cyanophyta (15 species), less often Dinophyta (5 species), Englenophyta (1 species) were found. The highest total phytoplankton abundance in water samples from both reservoirs was Cyanophyta, and the highest phytoplankton biomass was recorded in Bacillariophyta and Chlorophyta. At the same time, Englenophyta and Dinophyta were not found in the waters of the Kuyumazar reservoir. In the phytoplankton samples from Lake Tudakul, planktonic freshwater-brackish-water forms b-mesosaprobic predominated; brackish-water b- and b- and α-mesosaprobic species of algae prevailed.
